I thought I would make this a separate , so it doesn't detract from the original poster in the thread where this question was raised.
To start a new thread you click/tap on the text 'Start new discussion'. Within the specific part of the discussion forum that you want to post you will find this below the heading and description (and above the list of threads). For example, in this section:
Those exclusively using "Latest Content" won't see "Start New Discussion".
Get to "Start New Discussion" as follows.
Click on "Discussion Forum".
Then click on the appropriate classification for the new thread.
Then click on "Start New Discussion" immediately above the red ribbon.
